IMPROVEIVIENT IN SELF-LUBRIGATOR.

TO WHOM IT MAY CONCERN:

Be it known that I, JOHN BAGHELDER, of Norwich, in the county of New London, and State of Connecticut, have invented a nen7 and improved Mechanical Device for Applying Oil or other Liquid Substances for Lubricating Bearings of Shafting and Machinery.

The nature of' my invention consists in returning the lubricator afterbeing strained vto the shaft or journals continuously; and I do hereby declare that the following is a full and exact description of the construction and operation of the saine, reference being hadto the accompanying drawings, making a part of this specication, in which- Figure 1 is a front elevation with intervening supporting columns removed.

Figure 2, a longitudinal section parted vertically through the centre of the shaft; and

Figure 3 a transverse section.

In these fiigures, a represents a shaft supported in hangers b b. c represents a circular metallic plate, with a concave surface inclining towards the bearing, secured to and revolving with the shaft to be lubricated. The diameter of this plate c is determinedbythe speed of the shaft on which it is set, that in the model being calculated for about five hundred revolutions per minute. It is more readily applied te shafting by being made in halves. cl represents a conductor for the purpose of transferring the oil thrown ov by centrifugal force from the periphery of the plate e to the cavity in the capot' the hanger b. This conductor may be made of metal, wood,'or a string secured in the proper position. e represents a thin vertical plate-flange, secured to or cast'on the hub of the larger plate c to intercept thc oil ilowing from the plate c, and return it to the dripping-pan or fountain j". The bar g, the top of which is made of perforated sheet metal or wire cloth, is set in the bottom,

near oneend of-t'he' dripping-panf, and prevents the sediment and scum in and upon the returned oil from flowing into the end where the plate c is revolving in strained oil. represents a cap or hood covering the plate c, intcrcepting the oil thrown oif by it and supporting the conductor CZ. 'In mills where much lint or dust is floating in the atmosphere, the hood is madeto cover the whole bearing. That in the model is made narrow, and open, the better to show its operation;

In order to show the operation and effect of'iny invention, I have placed apuiley, 7a, on thc shaft a. When the` shaft'is driven at the requisite speed, the periphery of the plate c running in cleanoil placed in the drippingpan f, carries it up by centrifugal force above and into the conductor cl, which delivers itin the cavity in the cap of the hanger b. The oil then, after performing its otlice of lubricating, passes out at the ends et' the bearing in the usual Way, or may pass through a hole under the shaft into the larger part of the dripping-pan. The sediment then settles and the lighter portion of the oil passes through the strainer on the top of the bar g to bcagain taken up'and returned as before, using the sarneoil continuously and straining it as it is returned.

What I claim as my invention, and desire to secure by Letters Patent, is*

1. The revolving' plate c, the conductor d, the vertical flange e, the hood t', and the arrangement of the bar and strainer g in the dripping-pan. i

2. The combination ot' the revolving plate c and the conductor cl, or its equivalent, all for the purposes herein described.

JOHN BACHELDER.
